W'LADYSLAW O'IGWIGZ, OF GREEN WIGI-I, GONNEGTIGUT.

LOCK;

Application filed August 9, 1922. Serial No. 580,618.

the container and capable of defying those unfamiliar with its workings except by mere accident.

A further purpose is to produce a container that may be freely handled without opening, and even subjected to rough treatment without danger of loosening the lid.

Another aim is in the provision of a keyless lock that effectively bolts the cover to the base or releases it at will by one who has knowledge of its manipulations.

These objects are attained by the novel construction and combination of parts hereinafter described and shown in the annexed drawing, forming part of this disclosure, and in which: I

Figure 1 is a top plan view of a container made in accordance with the invention, the cover being shown in a raised position at a right angle to the body.

Figure 2 is a longitudinal sectional view taken on line 22 of Figure 1.

Figure 3 is a transverse sectional view taken on line 3-3 of Figure 2.

Figure 4 is a perspective view showing the locking bolt in detail.

In the type of box illustrated, the numeral designates a fiat level base having inset ends 11 and similarly inset walls 12, all of a uniform height.

A cover 13, identical with the dimensions of the base, is secured to the rear side wall by hinges 14:.

The extending ends of both the base and cover having formed in them transverse grooves 15 and 16, giving an ornamental appearance and also for another purpose here after seen.

Rigidly secured to the lower side of the cover or lid 13, near its center, is an arm 17 containing a slot 18 open at one of its side edges, acting as a catch by which the cover may be secured.

This arm passes down nearly to the bottom of the. box, through a casing 19 used to protect the operative parts of the device.

A bolt element 20 is slidably arranged below the casing 19, adjacent the rear wall of the box, this element having secured to it an arm 21 extending towards the front and adapted to slide on a raised block 22, being guided and held down by a leaf 28 fixed at a spaced distance over the block, the arm 21 being designed to enter the slot 18 and pre vent the cover from opening when in a forward position. v

The bolt 2-0 is secured to a slide 24 neatly fitted in the base 10, its, end projecting beyond the end wall and being provided with a groove 25 normally in register with the groove 15 in the base, the arrangement being such that the slide is undistinguishable,

from the base in which it operates.

Said slide, bolt and arm are normally held in a forward or engaging position by the thrust of a coiled compression spring 26 encircling a rod 27 set in the end of the box at one end and slidably entering an opening 28 in the registering end of the bolt 20, the spring abutting the bolt 20 and a collar 29 secured to the rod as shown.

In operation, presuming the cover closed,

the finger of an operator is placed to engage the slot 25, the slide and its attached parts drawn outwardly thereupon releasing the catch 17 permitting the cover to be I raised upon its hinges.

Obviously a similar operation is necessary when closing the cover in order to withdraw the arm to permit lowering the catch.

From the foregoing it will be seen that a keyless lock has been presented that is not likely to be negotiated with one unfamiliar with its operation.

Although the foregoing is descriptive of a preferred embodiment of the invention, it will be apparent that minor chianges in. construction can be made without material deviation from the scope of the invention as recited in the annexed claim.

Having thus described my invention,

what I claim as new and desire to secure by Letters P ate'nt, is

A locking device for a receptacle having a cover hinged to its rear wall, the base and cover of the receptacle extending beyond its vertical Walls and containing grooves in the adjacent surfaces, a slotted arm projecting down from said cover into 5 the receptacle, a casing in the receptacle through Which said arm extends, a slide movablein the upper surface of the base element, said slide having a groove registerable With one of the end grooves in the base, spring means for normally causing registration, and bolt elements carried by said slide adapted to engage the slot in said arm. In Witness whereof I aflix my signature.
